Products Description
Bently Nevada 3500/53 Overspeed Protection Module in stock
Bently Nevada 3500/53 is an electronic overspeed detection module for the 3500 machinery protection rack system. It receives pulse signals from speed probes to continuously measure rotating equipment RPM, providing overspeed alarm and trip protection functions. It supports 2oo2 or 2oo3 voting logic to meet safety protection requirements for critical rotating machinery.
This module is software configurable for speed threshold and relay action. It outputs 4-20mA analog speed signal for recorder or DCS system, with built-in self-diagnosis to detect sensor failure, open circuit and module hardware faults.
